A nurse is administering the Haemophilus influenzae type B vaccine (Hib) to a 6-month-old infant. Which of the following actions should the nurse take?
Administer the vaccine in the vastus lateralis muscle using a 25-mm (1-in) needle
Administer the vaccine subcutaneously in the abdomen using a 16-mm in needle
Administer the vaccine subcutaneously in the upper arm using a 13-mm (-n) needle.
Administer the vaccine in the dorsogluteal muscle using a 51 mm (2-in) needle
The Correct Answer is A
A. Administer the vaccine in the vastus lateralis muscle using a 25-mm (1-in) needle: For infants, the vastus lateralis muscle in the thigh is the preferred site for intramuscular (IM) vaccinations, including the Hib vaccine. A 25-mm (1-in) needle is an appropriate length for this muscle in a 6-month-old infant.
B. Administer the vaccine subcutaneously in the abdomen using a 16-mm (5/8-in) needle: The Hib vaccine is not administered subcutaneously. It is an intramuscular injection, and the abdomen is not the recommended site for this vaccine.
C. Administer the vaccine subcutaneously in the upper arm using a 13-mm (1/2-in) needle: The Hib vaccine is administered intramuscularly, not subcutaneously. The upper arm is used for intramuscular injections in older children. A 13-mm needle is too short for an intramuscular injection in the vastus lateralis.
D. Administer the vaccine in the dorsogluteal muscle using a 51-mm (2-in) needle: The dorsogluteal muscle is not recommended for infants due to the risk of damaging the sciatic nerve. A 2-inch needle is too long for this area in an infant.

Correct Answer is []
Explanation
Rationale for Correct Choices:
- Intussusception: The toddler's sudden onset of crying, drawing knees to the chest, and high-pitched cry are classic signs of intussusception. The "red jelly" stool (currant jelly stool) is also a hallmark symptom of this condition.
- Reinforce teaching with the guardian about hydrostatic reduction: Hydrostatic reduction is the treatment for intussusception, where a contrast material is used to reduce the telescoped bowel. It's an important intervention that should be discussed with the guardian.
- Palpate the toddler's abdomen for a mass in the upper quadrant: A palpable abdominal mass is a classic sign of intussusception, and the nurse should assess for this to help confirm the diagnosis.
- Abdominal pain: Monitoring abdominal pain is essential because it can be a significant indicator of worsening intussusception or any complications. The child is showing signs of severe pain, so it needs to be closely watched.
- Stool consistency: The "red jelly" stool is a key finding of intussusception, and the nurse should continue to monitor for this, as it is a clear indicator of bowel obstruction.
Rationale for Incorrect Choices:
- Prepare the toddler for an upper endoscopy with possible biopsy : An upper endoscopy with biopsy is used to assess gastrointestinal conditions like Celiac disease or gastroesophageal reflux. Intussusception is diagnosed through imaging techniques like ultrasound or a contrast enema, not an upper endoscopy.
- Request a prescription for a fat-soluble vitamin supplement: Vitamin supplements are more relevant to conditions like Celiac disease or other chronic malabsorption syndromes.
- Obtain a prescription for blood transglutaminase antibody testing: This test is relevant for diagnosing Celiac disease but is not needed for diagnosing intussusception, which requires imaging and clinical assessment for bowel obstruction.
- Gastroesophageal reflux: Gastroesophageal reflux does not typically present with the acute abdominal pain, "red jelly" stool, or the high-pitched crying observed in this toddler. It's more of a chronic condition associated with spitting up or regurgitation.
- Celiac disease: Celiac disease typically presents with gastrointestinal issues like diarrhea, abdominal distension, and failure to thrive, rather than acute symptoms like crying and "red jelly" stools.
- Gastroenteritis: While gastroenteritis may present with vomiting, diarrhea, and irritability, it does not explain the specific findings of a high-pitched cry, drawing knees to the chest, or the characteristic stool.
- Bone mineral densit: Bone mineral density is relevant to conditions like osteoporosis or rickets but is not related to intussusception. The focus here should be on monitoring gastrointestinal symptoms, particularly abdominal pain and stool consistency, not bone health.
- Sleep pattern: While sleep pattern can be affected by various conditions, it is not a primary concern in the management of intussusception. The toddler's acute symptoms (pain, vomiting, stool changes) should take precedence over monitoring sleep.
- Urine specific gravity: Urine specific gravity is typically monitored for dehydration or kidney function, but intussusception is not primarily associated with these issues.
- Request a prescription for blood transglutaminase antibody testing: This test is relevant for diagnosing Celiac disease but is not needed for diagnosing intussusception, which requires imaging and clinical assessment for bowel obstruction.
Correct Answer is C
Explanation
A. Gently cleanse the surgical site with sterile gauze: direct vigorous cleansing of the palate surgical site with gauze is generally avoided to prevent disruption of sutures. Oral rinses or specific gentle cleaning methods may be prescribed, but direct gauze wiping is usually not recommended.
B. Offer a pacifier with glucose syrup: acifiers and any sucking on objects (including straws, spoons, or toys) are typically contraindicated after cleft palate repair because the sucking motion puts stress on the suture line and can disrupt healing.
C. Apply elbow immobilizers to both arms: Elbow immobilizers prevent the infant from bending their elbows and bringing their hands to their mouth or face, which could disrupt the surgical sutures, cause trauma, or introduce infection to the delicate palate repair.
D. Place the infant in a supine position: A semi-upright position is usually preferred to reduce pressure on the surgical site and prevent aspiration, rather than placing the infant flat on their back.
